Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Along with the demand of people to the narrow frame effect of lower frame, there can be the design of bending zone when the lower frame designs. Fig. 1 is a schematic structural diagram of a partial area of a conventional array substrate, and specifically, fig. 1 shows a wiring situation at a lower right corner of the array substrate. As shown in fig. 1, in the non-display area 120 disposed around the display area 110, the ELVDD power supply lead 10, the gate driving circuit lead 12, and the ELVSS power supply lead 11 are sequentially arranged. Among them, the ELVDD power supply lead 10 is used to transmit an ELVDD power supply voltage to the pixel driving circuits in the display area 110, the ELVSS power supply lead 11 is used to transmit an ELVSS power supply voltage to the cathodes of the organic light emitting diodes OLED in the display area 110, and the gate driving circuit lead 12 is used to transmit circuit control signals (including a clock signal, a trigger signal, a power supply signal, and the like) to the gate driving circuit 13 located in the non-display area 120.
And one circuit structure of the pixel driving circuit may be as shown in fig. 2, the pixel driving circuit including a switching transistor T1, a driving transistor T2, and a storage capacitor Cst, a gate electrode of the driving transistor T2 being connected to one end of the storage capacitor Cst, a first electrode of the driving transistor T2 being connected to the other terminal of the storage capacitor Cst and an ELVDD power supply; the second electrode of the driving transistor T2 is connected to the anode of the OLED; the driving transistor T2 controls the amount of current flowing from the ELVDD power source to the ELVSS power source through the OLED to correspond to the value of the voltage stored in the storage capacitor Cst. At this time, the OLED emits light corresponding to the amount of current supplied from the driving transistor T2.
Obviously, when the OLED is driven to emit light by the pixel driving circuit, a large current is concentrated on the ELVSS power supply lead 11, which causes the ELVSS power supply lead 11 to generate heat in a concentrated manner, and thus the screen body is easily burned out.
In view of the above technical problems, embodiments of the present invention provide an array substrate, in which a power supply lead and a gate driving circuit lead on the array substrate are wired, so as to effectively solve the problem of heat generation of the power supply lead. Specifically, fig. 3 is a schematic structural diagram of a partial region of an array substrate according to an embodiment of the present invention.

Optionally, the Gate driving circuit 13 may be a Gate driving IC, or may also be a Gate In Panel (GIP) circuit, that is, a Gate driving chip is integrated on the Panel, so as to save the Gate driving chip, reduce the material cost, reduce the number of processes, and shorten the process time, thereby reducing the Panel cost and realizing a narrower frame.
In the embodiment of the present invention, the substrate base plate 101 may be a flexible base plate; the first power supply lead 21 and the gate driving circuit lead 12 are connected in a transition manner, and generally need to be arranged in different layers from the signal lines at the two ends thereof through a jumper wire. The first power supply lead 21 may be an ELVDD power supply lead or an ELVSS power supply lead, and considering that the current on the ELVSS power supply lead 11 is large, the generated heat may burn out the screen body, so that, optionally, the first power supply lead 21 in the embodiment of the present invention is an ELVSS power supply lead.
The circuit control signal may include a clock signal, a trigger signal, and a power signal, and correspondingly, the gate driving circuit lead 12 includes leads corresponding to the circuit control signal one by one to respectively transmit different signals.

Illustratively, as shown in fig. 4, the plurality of first power supply leads 21 are divided into two first power supply lead groups 20, and in this case, the gate driving circuit leads 12 are all disposed between the two first power supply lead groups 20. In addition, when the plurality of first power supply leads 21 are divided into two first power supply lead groups 20, a part of the gate driving circuit leads 12 may be disposed between the two first power supply lead groups 20, and another part of the gate driving circuit leads 12 may be disposed on the other side of one of the first power supply lead groups 20. The present invention does not limit the number of the first power supply leads 21 and the specific arrangement of the first power supply leads 21 and the gate driving circuit leads 12, and the first power supply leads 21 are arranged in a dispersed manner and a heat dissipation space is provided through the region where the gate driving circuit leads 12 are located, so that the concentrated heat generation of the first power supply leads 21 can be avoided, and the heat generation problem of the first power supply leads 21 can be improved.
In the embodiment of the invention, a plurality of first power supply leads and a plurality of grid drive circuit leads which extend along a first direction and are distributed along a second direction are arranged in a non-display area of a substrate; the plurality of first power supply leads are divided into at least two groups of first power supply lead groups, wherein each group of first power supply lead groups comprises at least one first power supply lead, and a plurality of grid driving circuit leads are arranged between two adjacent groups of first power supply lead groups. The first power supply leads are separated by the grid drive circuit leads, so that the first power supply leads are distributed in a dispersed manner, and the concentrated heating of the first power supply leads is avoided; and the heat that the first power lead wire in each group of first power lead wire group that distributes produces can more evenly spread to the region at grid drive circuit lead wire place, has improved the thermal diffusion effect on the first power lead wire, has effectively reduced the heat that gathers on the first power lead wire. Therefore, in the embodiment of the invention, from the angle of layout wiring, the plurality of first power supply leads and the plurality of grid drive circuit leads are reasonably wired, and the plurality of first power supply leads are distributed, so that the distribution concentration of the first power supply leads is reduced, heat generated by the first power supply leads can be effectively diffused to the region where the grid drive circuit leads are located, and the problem of heat generation of the first power supply leads is solved.

Therefore, the bending performance of the first power supply lead 21 and the gate driving circuit lead 12 can be improved, the first power supply lead 21 and the gate driving circuit lead 12 are prevented from being broken, and abnormal display of the display device is prevented.
Optionally, fig. 5 is a schematic structural diagram of a partial region of an array substrate according to another embodiment of the present invention. As shown in fig. 5, based on the above embodiments, the array substrate of this embodiment may further include a first power signal receiving bus 14 and a first power signal output bus 15, which are disposed in the non-display area 120 on the substrate 101, wherein the first power signal receiving bus 14 is configured to receive a first power voltage signal, and the first power signal output bus 15 is configured to output the first power voltage signal to the display area 110;
the first end of each first power lead 21 is electrically connected to the first power signal receiving bus 14, and the second end of each first power lead 21 is electrically connected to the first power signal output bus 15, wherein the first power signal output bus 15 is located at a side of the bending region close to the display region, and the first power signal receiving bus 14 is located at a side of the bending region far from the display region.
At this time, the first power supply lead 21, the first power supply signal receiving bus 14 and the first power supply signal output bus 15 may be disposed around the gate driving circuit lead 12, and heat generated by the first power supply lead 21, the first power supply signal receiving bus 14 and the first power supply signal output bus 15 may be diffused to an area where the gate driving circuit lead 12 is located, so that heat on the first power supply lead 21 is effectively reduced, and the heat is uniformly distributed.
In this embodiment, since the ELVSS power supply voltages provided to the OLEDs in the display area are the same, the wiring around the display area in the non-display area can be performed in a bus manner, and thus, the wiring in the non-display area can also be simplified.
Optionally, the first power signal receiving bus 14 and the first power signal output bus 15 are located on the same layer, that is, the first power signal receiving bus 14 and the first power signal output bus 15 may be formed in the same process, so that the process flow is reduced, and the process cost is reduced. Meanwhile, a plurality of IC output pads 18 arranged along the second direction Y are disposed on the non-display area 120 of the array substrate, and the IC output pads 18 are used for binding the driving IC and are correspondingly electrically connected with pins of the driving IC; and the first power signal receiving bus 14 is electrically connected to the corresponding IC output pad 18 to obtain the first power voltage from the driving IC.
In addition, with reference to fig. 5, the array substrate may further include a plurality of control signal receiving traces 16 and a plurality of control signal output traces 17, which are disposed in the non-display area 120 on the substrate base plate 101; the first end of the control signal output wire 17 is electrically connected with the gate drive circuit 13, and the second end of the control signal output wire 17 is electrically connected with the control signal receiving wire 16 in a one-to-one correspondence manner through the lead 12 of the gate drive circuit; the control signal receiving trace 16 is electrically connected with the corresponding IC output pad 18 to acquire a circuit control signal from the driving IC; the control signal receiving trace 16 is electrically insulated from the first power signal receiving bus 14, and the control signal output trace 17 is electrically insulated from the first power signal output bus 15. For example, the control signal receiving trace 16 and the control signal output trace 17 may be located on the same layer, the control signal receiving trace 16 may be disposed across the first power signal receiving bus 14 to be electrically insulated from the first power signal receiving bus 14, or the control signal receiving trace 16 and the first power signal receiving bus 14 may be located on different layers.
Optionally, in the at least two first power supply lead groups and the gate driving circuit leads, at least one of the first power supply lead groups is closest to one side edge of the substrate base plate. For example, referring to fig. 3 to fig. 5, at least one first power lead group always exists on the substrate 101, and is disposed at the outermost side of the substrate 101, at this time, because the signal (current) in the first power lead 21 is stronger, the antistatic capability of the first power lead 21 is stronger, and the static electricity generated at the side end of the screen body can be resisted better, so that the antistatic capability of the screen body is improved; in addition, since each of the first power supply leads 21 is electrically connected to the first power supply signal receiving bus 14 and the first power supply signal output bus 15, even if the outermost first power supply lead 21 disposed on the substrate board 101 is damaged by static electricity, the transmission of the first power supply voltage by the other first power supply leads 21 is not affected, and the reliability of the panel is improved.
Optionally, fig. 6 is a schematic structural diagram of a partial region of an array substrate according to another embodiment of the present invention. As shown in fig. 6, the non-display area 120 includes a bending area 121, the first power supply lead 21 and the gate driving circuit lead 12 both penetrate through the bending area 121 in the first direction X, and a plurality of holes 19 are formed in portions of the first power supply lead 21 and the gate driving circuit lead 12 located in the bending area 121, so that the bending performance of the first power supply lead 21 and the gate driving circuit lead 12 can be improved, the first power supply lead 21 and the gate driving circuit lead 12 are prevented from being broken, and the display device is prevented from displaying abnormally.
However, it is considered that the opening of the first power supply lead 21 reduces the width of the first power supply lead 21, which increases the impedance of the first power supply lead 21 and thus increases the heat generation of the first power supply lead 21. Therefore, the embodiment of the invention improves the heating problem of the first power supply lead 21 by expanding the whole heat dissipation area of the first power supply lead 21 while ensuring the bending performance of the first power supply lead 21.
Fig. 7 is a schematic structural diagram of a partial region of an array substrate according to yet another embodiment of the present invention. As shown in fig. 7, the first direction X is parallel to one side (right side in the figure) of the base substrate 101, and an extension line 30 (shown by a dashed line frame in the figure) of a part of the first power supply lead 21 in the first direction X intersects with the display area 110. Compared with the existing wiring (the wiring shown in fig. 1), the lead area of the first power supply lead 21 in the embodiment is expanded toward the middle of the substrate base plate 101, so that a larger number of first power supply leads 21 can be arranged or the width of the first power supply lead 21 can be increased, thereby, on one hand, more space is provided for increasing the width of the first power supply lead 21, further the impedance of the first power supply lead 21 is reduced, on the other hand, the heat dissipation area of the first power supply lead 21 is further increased, the heat dissipation of the first power supply lead 21 is facilitated, and the heat generation problem of the first power supply lead 21 is improved.
Specifically, as shown in fig. 8, the array substrate may further include a plurality of second power supply leads 31 disposed in the non-display area 120 on the substrate base plate 101, extending along the first direction X and arranged along the second direction Y, the second power supply leads 31 are configured to transmit a second power supply voltage signal to the display area 110, and the second power supply leads 31 are located on one side of any one of the first power supply leads 21, which is far away from the side (the right side in the figure) of the substrate base plate 101. Illustratively, the first power supply lead 21 is an ELVSS power supply lead, the second power supply lead 31 is an ELVDD power supply lead, and the first power supply lead 21 and the second power supply lead 31 are adjacently disposed. Currently, referring to fig. 1, the ELVDD power supply leads are all located on the extension lines of the display area 110 corresponding to the ELVDD power supply signal transmission traces, so that the wiring area of the ELVSS power supply leads is small. Considering that the ELVDD power supply voltages required by the pixel driving circuits in the display area 110 are the same, fewer ELVDD power supply leads may be arranged to electrically connect the ELVDD power supply leads to more ELVDD power supply signal transmission traces in the display area, and further, in this embodiment, the lead area of the second power supply lead 31 may be compressed (the number of the second power supply leads 31 is reduced), and the vacant area is used for disposing the first power supply lead 21, so as to increase the heat dissipation area of the first power supply lead 21.
Similarly, the present embodiment may also transmit the second power voltage signal (ELVDD power voltage signal) to the display area 110 by routing a bus at the periphery of the display area 110. Optionally, referring to fig. 8, the array substrate further includes a second power signal receiving bus 32 and a second power signal output bus 33, which are disposed in the non-display area 120 on the substrate 101, wherein the second power signal receiving bus 32 is configured to receive a second power voltage signal, and the second power signal output bus 33 is configured to output the second power voltage signal to the display area 110;
a first end of each second power supply lead 31 is electrically connected with the second power supply signal receiving bus 32, and a second end of each second power supply lead 31 is electrically connected with the second power supply signal output bus 33; the second power signal receiving bus 32 is electrically connected to the corresponding IC output pad 18 to acquire a second power voltage signal from the driver IC.
In addition, the second power supply lead 31 penetrates through the bending region 121 in the first direction X and is connected to the display region 110, and a plurality of holes are formed in a portion of the second power supply lead 31 located in the bending region 121, so that the bending performance of the second power supply lead 31 can be improved, the second power supply lead 31 is prevented from being broken, and abnormal display of the display device is prevented.
Optionally, the first power supply lead 21, the gate driving circuit lead 12, and the second power supply lead 31 are located in the same layer, that is, the first power supply lead 21, the gate driving circuit lead 12, and the second power supply lead 31 may be formed in the same process, so that the process flow is reduced, and the process cost is reduced.
Optionally, in this embodiment, each control signal output trace 17 extends along the first direction X, that is, each control signal output trace 17 is linearly arranged, so that the process difficulty caused by bending and wiring is avoided.
